I need help: not everyone can join!

[GPSRT]

I've got a few users that CAN join, and a few that can't.

THey do traceroutes and see me just fine, they can join my vent server just fine, they can even join other ts servers just fine, but for some reason, can't join mine.

Any tips?

69.63.50.183:8767 pass is scarlet, i'm on now... see if you can join.

Why in the world can no one answer this question?!?! Everyone I ask doesn't know, they just say IDK befor even trying to find out the problem..
